Синопсис (Synopsis)

     #include <sys/acl.h>

     acl_t
     acl_from_text(const char *buf_p);

Описание (Description)

The acl_from_text() function converts the text form of the ACL
     referred to by buf_p into the internal form of an ACL and returns a
     pointer to the working storage that contains the ACL. The
     acl_from_text() function accepts as input the long text form and
     short text form of an ACL as described in acl(5).

     This function may cause memory to be allocated.  The caller should
     free any releasable memory, when the new ACL is no longer required,
     by calling acl_free(3) with the (void*)acl_t returned by
     acl_from_text() as an argument.

---

Возвращаемое значение (Return value)

On success, this function returns a pointer to the working storage.
     On error, a value of (acl_t)NULL is returned, and errno is set
     appropriately.

---

Ошибки (Error)

If any of the following conditions occur, the acl_from_text()
     function returns a value of (acl_t)NULL and sets errno to the
     corresponding value:

     [EINVAL]           The argument buf_p cannot be translated into an
                        ACL.

     [ENOMEM]           The acl_t to be returned requires more memory
                        than is allowed by the hardware or system-
                        imposed memory management constraints.
